Previous research suggests that the collection and testing of measure-to-measure and day-to-day variation across a multi-site operation in a standard real-time Statistical Process Control (SPC) solution can be problematic at best. Replicating the full measurement process for mean and range in real-time not only strains resources, but may not provide an adequate indicator of measure-to-measure variation, thus resulting in exceedingly narrow control limits for day-to-day variation. A proposed solution to thi
